PHILADELPHIA (Nov. 23, 2015) – Philadelphia District Attorney R. Seth Williams today announced that George D. Mosee, Jr. has been promoted to be the office’s new First Assistant District Attorney and Kathleen Martin will assume the newly created position of Chief of Staff, General Counsel and Chief Integrity Officer.
“It is a pleasure to make today’s announcement because all of us here at the Philadelphia District Attorney’s Office want to be effective and do our jobs with the highest levels of service that we can provide. We also want to be the best team that we can for the people of Philadelphia,” said Seth Williams. “I have full confidence in George Mosee and I am excited to have him in the role as my First Assistant District Attorney because George is a well-respected prosecutor and someone who has dedicated his career to this office.”
“It’s humbling to be asked to serve as the First Assistant District Attorney and so I am going to do all I can to help District Attorney Williams with his ongoing reforms and initiatives to make this office the very best it can be,” added George Mosee. “My family and I love this city and so as a prosecutor and a Philadelphian I’m always ready to make Philadelphia’s neighborhoods and streets safer.”
Since 2002, Mosee has been serving as the Deputy District Attorney in charge of the Juvenile Division of the Philadelphia District Attorney’s Office. The Juvenile Division includes the Juvenile Drug Treatment Court Program, Juvenile Prosecution Unit, Habitual Offender Unit, Child Support Unit and Youth Aid Panels. Deputy Mosee joined the office in 1988 and served in various units including Motions, Major Trials, Federal Alternatives to State Trials as a Special Assistant United States Attorney, Asset Forfeiture as Chief, and Chief of the Dangerous Drug Offender Unit. From 1995 to 2002, Mr. Mosee was the Deputy District Attorney in charge of the Narcotics Division.
“Kathleen Martin will be my new Chief of Staff, General Counsel and Chief Integrity Officer,” said Seth Williams. “Ms. Martin brings experience in Pennsylvania criminal law as well as a deep knowledge of the history and unique facets of Philadelphia courts and criminal practice. I am very proud of the work we have accomplished in the Philadelphia District Attorney’s Office so far and am excited about the opportunity to strengthen the office and to help the 600 men and women of the office make a difference in our city.”
Chief of Staff Kathleen Martin added, “District Attorney Seth Williams has an incredible reputation of being an accomplished prosecutor who isn’t afraid to take on crime and corruption regardless of where the facts may lead him. I am looking forward to working with District Attorney Williams and the office’s highly skilled group of prosecutors and professionals to make this office even more effective moving
Ms. Kathleen Martin is a 1992 graduate of Temple University School of Law and a 1989 graduate of Villanova University. For much of her twenty-three year career, she has practiced criminal law in the state and federal courts in Philadelphia where she developed a reputation as a fierce litigator who is respected by judges, prosecutors and defense attorneys alike. Martin’s attention to detail and ability to quickly synthesize information will be enormous assets to District Attorney Williams and the office.
Most recently, Ms. Martin was appointed as an Assistant District Attorney in Pike County, Pennsylvania where she represented the Commonwealth in cases ranging from murder to distribution of narcotics. In 2014, she assisted the Pennsylvania State Police and other law enforcement agencies during the month long manhunt for Eric Frein after the tragic assassination of Corporal Bryon Dickson and wounding of Trooper Alex Douglas at the Blooming Grove, Pennsylvania State Police Barracks.
On the personal side, in 2013, Ms. Martin fulfilled a lifelong goal of traveling to Africa spending extensive time in countries including South Africa, Malawi, Zambia, Tanzania, Ethiopia and India. The highlight of the trip was visiting the village in Ethiopia that was the birthplace of one of her sons. Following her visit to her son’s village, Ms. Martin and her husband established a foundation that they hope will, for the first time in the village’s history, provide some of its residents with secondary education and a pathway out of subsistence living.
“Finally, I would be remiss if I did not thank former First Assistant Ed McCann for his many years of service and friendship,” said Seth Williams. “Ed was instrumental in helping the office institute many of the reforms of which we are all proud of and spent twenty-six years in this office as a trusted advisor and terrific prosecutor. The City of Philadelphia is a safer place because of the extraordinary service, hard work and commitment of Ed McCann.”
McCann submitted his letter of resignation today, and all three changes are effective immediately.
